Abbreviations: R1 = Ranger Classic, R2 = Ranger Gold, R3 = Rowan Ranger, A = Hubbard Red JA, CY = CY Gen 5 × JA87, M = M22 × JA87. SE est = standard error of the estimate. * univariable analysis; † in percentages, mean ± SE; ‡ scale 0–4, median (IQR); values in the same row not sharing the same superscript are significantly different at p < 0.05 (Sidak correction or Dunn’s multiple comparisons test).
